I’m not sure where you got the “1GB per month” part, but all it says is that will use up to 1gb of data on your drive. That’s up to, and it’s not all being uploaded. I would think that much is obvious. It’s also data that gets purged by storage sense when your drive storage is low so you aren’t really “paying to store or” this is also something you are asked if you want to do when installing windows, very similar to just about every mainstream Linux distro out there. Not to mention every Linux distro is also pinging various URLs when you first boot it so I don’t know why that’s not upsetting you
